South TX Scout Day: Pitcher Data Dive


Prep Baseball Texas Staff

On Saturday, October 11th, the PB Texas staff traveled to Calallen High School in Corpus Christi, TX, to host the South Texas Scout Day.

Nearly 100 players made their way to Calallen HS this past weekend and participated in a pro-style workout, gathering unrivaled access to data through our state-of-the-art tech partners, as well as in-depth scouting analysis from our Prep Baseball Texas staff.

We have already released a Statistical Analysis for the event, that highlighted the top statistical performers, as well as our scouting takeaways on the event's top performers. We also highlighted some of the top positional players within this Data Dive story.

Today, we will be looking at the top measurable data performers from the event, found below.

2 John Reyna TX Psja Early College H S 2027 RHP 2157 rpm

5 Julian Colsa TX Veterans Memorial High School 2026 OF 1986 rpm

Spin Rate: This metric calculates the rate of spin on the baseball as it leaves the pitcher’s hand, measured in revolutions per minute (rpm). Historical data shows that high-spin fastballs lessen the impact of gravity, allowing for more ‘rise’ (or less fall, in other words) as it carries through the zone. Low-spin fastballs typically indicate the pitch has greater horizontal action, often making it tougher to square up, but generally easier to make contact with, leading to more ground balls, while high-spin fastballs show a correlation with swings and misses.

INDUCED VERTICAL BREAK (AVG.)

Rank Name State School Class Pos IVB (avg)
1 Joshua Benitez TX w.b Ray Texan 2027 RHP 19.1 in
2 Cedric Smith TX Calallen H S 2028 RHP 17.6 in
3 Julian Colsa TX Veterans Memorial High School 2026 OF 16.5 in
4 jaime cordova TX La Joya Palmview 2026 RHP 15.7 in
5 Kaileb Gogo TX Calallen H S 2029 LHP 15.5 in

Induced Vertical Break: Used in short form as "IVB," this metric is most important on fastballs for creating rise and on curveballs for creating depth – it can also have some use when measuring sliders and cutters as well. Sliders tend to be closer to zero inches while cutters are generally between 5 and 15 inches. Usually fastballs and curveballs with large IVB have higher spin efficiencies as well. Sliders generally have very little (closer to zero) IVB and very low spin efficiencies. You could also categorize IVB into spin rate as this is part of the “useful movement” you’re looking for. IVB is also a huge part of vertical approach angle.

HORIZONTAL MOVEMENT (AVG.)

Rank Name State School Class Pos HM (avg)
1 Mason Colsa TX Veterans Memorial High School 2028 SS 14.9
2 Diego Castillo TX Weslaco High School 2026 RHP 14.6
3 jaime cordova TX La Joya Palmview 2026 RHP 13.4
4 Zaine Martinez TX Gregory-Portland H S 2027 LHP -10.9
5 Kaileb Gogo TX Calallen H S 2029 LHP -10.8

Horizontal Break: Outlined on TrackMan’s own website: “... horizontal movement is measured in inches between where the pitch actually crosses the front of home plate side-wise, and where it would have crossed home plate side-wise if had it traveled in a perfectly straight line from release. A positive number means the break was to the right from the pitcher’s perspective, while a negative number means the break was to the left from the pitcher’s perspective.”
